Beam column joint rotation

[SemiPE]

Hi all, some programs give the amount of joint rotation per load case, I wonder what is the use of this? for both RC structure and Steel structure.

Rotations and deflections give a clear picture of how the structure is deforming under load.

If you design a bridge bearing pad, you may want to know the joint rotation at the location of bearing pad.
